Some 2000 persons died and many others were injured, … These don’t even fall in the category of megatsunamis, which are generally the result of huge objects falling into oceans and generating waves that are few hundred meters in height. In the event of mass wasting, debris flows may slide into the reservoir, resulting in a lake tsunami. One such example is the 1963 Vajont Dam Disaster in Italy.
